AUTOMOBILE-CRANK.

To all whom it may concern Be it known. that we, CLAnnncn'A. BAILEY and LOUIS C. SOILEAU, citizens of the United States, residing at Rayne, in the parish of Acadia, State of Louisiana, have invented a new and useful Automobile-' Crank, of which the following is a specification, r a

The device forming the Subject matter of this application is a crank, adapted to be applied to the shaft of an internal combustion engine of the kind used on automobiles, motor boats and the like.

The invention aims .to provide novel means whereby, when a back fire occurs, the swinging movement of the handle or crank will be stopped, thereby avoiding an injury to the operator.

It is within the province of the disclosure to improve generally and to; enhance the of devices of'that typeto which the utility present invention appertains. p p

With. the above and other objects in view whichfwill appear as the description T proceeds theinvention resides inthe combination" and arrangement of'partsand in the details of. construction hereinafter described and claimed, ;.it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings:-

li Figure 1 shows in top plan, a device constructed in accordance with the present inventlon, parts being shown in section;

Fig. 2 is a front elevation of the device shown in Fig..1;-

-- Fig. 3 is a section taken on the line 3 3 of Fig. 1, distant parts being omitted;

Fig. 1 is an elevation showing one of the strikers;

Fig. 5 is a fragmental bottom plan of the handle or crank; I i

Fig. 6 is a fragmentalperspective view illustrating a portlon of the pawl; and

Fig. 7 is a diagram alluded to in setting forth the operation of the device.

In carrying out the present invention I there is provided a support, which may be fashioned variously without departing from the spirit of the invention or jeopardizing the utility of the structure hereinafter described. The support may include a back plate 1 carrying a Ill-shaped frame made up Specification of Lettersrat'ent. Pa,1]@nt@dLM3 y @1, 191g, h Application filedNovember 10,1917. "Serial 110.2013 13. i l

of base 2 and forwardly presented ears 3 and-4. A pivot element-dismounted in the ears 3. Ari-striker 6, in theform of a plate,

is mounted to swing between the ears 3, on j a the pivot element 5. The striker 6, as shown in Fig, 3, includes a straight rear edge 7,

ears 3, limits the upper swinging movement of the striker on the pivotelement 5. a One corner of the striker 6 is rounded, as shown at 8, so that the striker can swing down- 7 wardly on the pivot element 5. Theforward edge of the striker 6 is downwardly and forwardly inclined, as shown at 9. "A spring tongue lO bears against the straight lower its rear-end, as shown at 12, to the base 2.

The earsjs o carryla pivot element 14 on which is mounted to swing, a striker 15, re:

*sembling the striker 6 in all essential .par-

ticulars, aside-from the fact that thedownwardlyand forwardly inclined edge9 of the striker 6 is replaced, in the striker15, by an upwardly and ,rearwardly inclined edge 16,

.as shown in Fig. 4. A spring tongue A2 which, co-acting with the base 2, between the 1 edge 11 ofthe striker 6 and is secured at" i The, tongue 10 serves to maintain the rear ;;f

. edge 7 of the striker yieldably engaged with 1 bears on the upper edge of the striker 15 and 1 is secured as shown at 1-3 to the base 2, the tongue 42 having the functions of the tongue 10 of Fig. 3.

An engine shaft 17a journaled for rotaj tion in the' base 2. and in the back plate 1 and is provided with an enlarged end 18 defining a shoulder 19 which coacts with the forward faceof. the base 2. A collar 20 is secured to. the end 18 of the engine shaft and includes a reduced extension 21 defininga shoulder 22 having a reduced tip 23 forming a shoulder 24. A ratchet wheel 25 is mounted on the extension 21 and abuts against the shoulder 22, the ratchet wheel having one ormore rearwardly projecting a lugs 26, which, being engaged in notches 27 inthe forward end ofthe collar 20, connect theratchet wheel and the collar 20, for simultaneous rotation, together with the engine shaft 17.

The numeral 28 marks a handle of any desired kind, including an eye 29, mounted to swing on the extension 21 of the collar 20, in front of the ratchet wheel 25. The handle 28 is maintained on the part 21, for swingingmovement, by means of a washer 30, a asg agamath shoulder 24 and held by a nut 31th rea ded on the tip 23. At 32 there"appearsja pawl, including a head pivoted at 53 to thehandle28,*the pawl end oftl'iespringfl l;being securedat, 35m" the handle 28/"The' handle 28 is p1- w'ided" I On-fis lower edge with a O 'eBG.in'i ot the str1ker;6.,

During thisoperation, and while the pawl 32 isclicking over-the teeth of the ratchet wheel 25, the spring latch 37mins handle 28 rides on the periphery Q of the' head 40,'fas shown inFig. (3,but does not engage 'withthe shoulder tl; The halldle-28 may :bemoved-e through an arc-of anyff desired extent, tocrank upthe eng ne, and.
